Success stories

Dirk Wagner, Digitalchef of the City Solingen

City Solingen

Situation: After the coronavirus pandemic the public transport could not be sufficiently adapted to the new health regulations, which meant that not all of the students were able to get to school.

Goal: A hybrid concept which enables half of the class to stay at home and the other half to come to school on an alternative base. This minimises the risk of infection.

Execution: Sdui has been chosen by the school authorities, as a uniform solution to support all schools with presential and remote lessons. We analyse the elements required to implement hybrid lessons and made integration of existing softwares possible.

Result: The schools were given Sdui: a flexible and GDPR conform platform as a basis, in combination with other solutions. Now the change between face-to-face and remote lessons is truly easy and works without any problems. To this day, the model in Solingen is a perfect example for successful hybrid lessons.

Situation: In February 2020 a hurricane lead to a wind speed of up to 200 kph. This lead to the majority of lessons in school and activities in daycare centres being cancelled. Parents had to be informed in an efficient and quick manner.

Goal: Ensure that all the important information reaches the relevant people so that everyone can stay safe.

Execution: The school management informed everyone about the regulations in relation to the storm for the next day using the Sdui app. The read receipt enabled them to see who had already been informed. The parents were then able to decide, whether they would send their children to school. If not, they could confirm their absence via telephone or using the Sdui app.

Result: Sdui enabled the school management to ensure the safety of the pupils and ensure that everyone is informed. The app also meant that the communication was more efficient and consistent.

Why did we develop Sdui?

The Sdui team, summer 2022

Sdui was developed to provide a solution to real problems faced by schools today and to help them prepare for the future. Our team includes former students and teachers, as well as individuals who can identify and address the daily challenges faced by schools. We strive to continuously adapt and expand our platform to meet the needs of teachers, students, and parents, making their lives easier.

We understand that digital transformation is not a one-size-fits-all process and that everyone has unique wishes, needs, and demands. We listen to our users and personalize the app to their specific requirements. The ultimate goal of Sdui is to create a safe space where all relevant people can come together, utilizing features and support that simplify their everyday life. This space is called the “Digital School”.

Our vision of a digital school

Our vision for a successful digital school is based on close collaboration with schools and preschools. We do not aim to replace face-to-face classes, but rather to support them and ensure that lessons can continue even during crises. Our goal is to create a digital environment that replicates the feeling of a physical school, with all members coming together in one digital space. We want to facilitate communication between all members of the school through text, call, and video call. Our dream is to create schools where information is easy to find and there is no need to search or figure things out. The app’s features and tools are designed to meet the needs of each school, ensuring that everything necessary is readily available. The digital school is also secure, not only because it is GDPR compliant, but also because it protects students from cyberbullying and teachers from stress. In situations where face-to-face learning is not possible, teaching can still continue digitally.

This is our vision for the digital school, and it is what Sdui creates.
